摘　　要：为解决移动设备接入Internet的需求,提出了基于GPRS和PPP接入Internet的思想,在论证总体设计方案的基础上,介绍了嵌入式微处理器芯片S3C2410以及支持GPRS Class8的高速无线通信模块MC35T。以S3C2410处理器为硬件核心,以ARM Linux为操作系统构建了一嵌入式Internet接入平台,描述了其硬件平台结构及运行流程,分析了其三层软件体系结构,详细讲解了软件体系最上层的PPP拨号软件包的实现。In order to solve the requirement of mobile equipment connected with Interent,this paper puts forward an idea connecting with Internet based on GPRS and PPP. On the basis of discussing the general designing scheme the paper introduces embedded MPU S3C2410 and high- speed wireless communication module MC35T supporting GPRS Class8. Besides this paper describs the hardware structure and working process of the embedded Internet- connected platform, which regards S3C2410 as core of hardware and Arm Linux as OS. Then the three layered software is described and the realization of PPP dial- up software package based on this platform is explained in detail.
